A. Embodiments of a Foldable Container in an Open Position

FIG. 1 depicts an isometric view of an embodiment of foldable container 100 that is in an open position. Foldable container 100 is configured to be self-standing in an open position and collapse into a folded position.

Foldable container 100, in one embodiment, includes a plurality of foldable walls. The foldable walls are foldable wall 110, foldable wall 120, foldable wall, 130 and foldable wall 140, each of which are connected to bottom portion 150 (as shown in at least FIG. 3). The combination of foldable walls 110, 120, 130, 140 and bottom portion 150 create an open area within foldable container 100 such that contents (not shown) may be placed within foldable container 100 via opening 160 (or open end).

The foldable container 100 is comprised of a material having various properties (e.g., compressive strength, rigidity, flexural strength, modulus of rupture etc.) that enables foldable container 100 to be in a stand-alone open position, as depicted in at least FIG. 1. Additionally, the material of the foldable container provides sufficient strength such that contents within the foldable container are less likely to rupture or puncture the foldable container through the bottom portion and/or foldable walls as compared to a convention paper bag.

Moreover, the material of the foldable container provides sufficient strength that enables the foldable container to maintain its stand-alone open position when one or more other foldable containers (that include contents) are stacked on top of the foldable container.

For example, the foldable walls include a substantially rigid material such that the foldable container does not collapse under the weight of additional foldable container stacked on top of the foldable container (see FIG. 10). The material may slightly flex during the folding to facilitate in collapsing the foldable container.

The material of foldable container can be, but is not limited to, cardboard, corrugated cardboard, etc. It should be appreciated that the material is not required to be a single sheet of paper. Additionally, the material of the foldable container may be recyclable (e.g. recycled cardboard).

In various embodiments, foldable container 100 includes handle 170 and handle 172 to facilitate in carrying foldable container. Handles 170 and 172 may be the same material as the foldable walls and/or bottom portion or may be a different material, such as wire.

Foldable container 100 includes a plurality of foldable seams to facilitate in folding or collapsing foldable container into a collapsed position, similar to the folding of a conventional paper bag into a collapsed position.

For example, foldable wall 110 includes foldable seam 111, foldable wall 120 includes seam 121, foldable wall 130 includes seam 131 (see FIG. 4), and foldable wall 140 includes seam 141 (see FIG. 7).

Moreover, there is a foldable seam at each joint where each foldable wall abuts another. For example, foldable seam 112 at the joint of foldable wall 110 and wall 120, foldable seam 122 at the joint of foldable wall 120 and 130, foldable seam 132 at the joint of foldable wall 130 and foldable wall 140, and foldable seam 142 at the joint of foldable wall 140 and foldable wall 110. Similarly, there is a foldable seam at each joint where each wall abuts bottom portion 150. In one embodiment, the foldable seam is a crease or a fold in the material of the foldable container 100.

In another embodiment, as will be described in further detail below, the foldable seam is a hinge portion that joins the various portions of the foldable container. Additionally, the foldable seam comprises a different material than the material of the foldable walls and/or bottom portion of the foldable container.

Various figures presented herein, provide views of foldable container in an open position. For example, FIG. 6 depicts a side view of foldable container 100, FIG. 7 depicts an opposite side view of foldable container 100 and FIG. 11 depicts a cross-sectional side view of foldable container 100. Moreover, FIG. 8 depicts a top view of foldable container 100.

It should be appreciated that although foldable container 100 has similar features and functionality as a conventional paper bag, foldable container 100 is not a paper bag. Additionally, although foldable container 100 has similar features and functionality as a nesting of conventional paper bags (e.g., doubling up of paper bags), foldable container 100 is not a nesting of paper bags.

It should also be appreciated that foldable container 100 may be configured in various shapes, sizes and colors. Additionally, various logos and/or advertising may be printed on the foldable container.

B. Embodiments of a Foldable Container in a Folded/Collapsed Position

As described herein, foldable container 100 may be folded into a collapsed position such that it is flat. The folding of foldable container 100 is enabled by the various foldable seams, as described above.

FIG. 2 depicts an isometric view of foldable container 100 in a partially folded position. For example, foldable container 100 is partially folded along the various foldable seams, such as foldable seams 111 and 121.

FIG. 3 depicts an isometric view of foldable container 100 in a partially folded position that is continuation of the folding, as depicted in FIG. 2. For example, foldable container 100 is partially folded along the various foldable seams such that foldable container is flat.

FIG. 4 depicts an isometric view of foldable container 100 in a fully folded (or collapsed) position that is a continuation of the folding, as depicted in FIG. 3. For example, foldable container 100 is folded along the various foldable seams such that foldable container is flat.

FIG. 9 depicts an isometric view of foldable container 100 in a fully folded (or collapsed) position stacked with a plurality of other foldable containers in the same folded position.

C. Embodiments of Stacked Foldable Containers

As described herein, foldable container 100 is able to be vertically stacked with other foldable containers such that foldable container 100 is not deformed from the weight of the other foldable containers stacked on top of foldable container 100.

FIG. 10 depicts an isometric view of foldable containers in a stacked orientation. For example, another foldable container is stacked on top of foldable container 100 such that foldable container 100 does not collapse under the weight of the other foldable container containing contents (not shown).

It is envisioned that foldable containers may be stacked during transport and not fall over. For example, the foldable containers may be stacked in back of a car or in a moving van. As a result, the foldable containers are less inclined to fall over and potentially break or damage the contents within the foldable containers.

D. Additional Embodiments of a Foldable Container in an Open Position

FIG. 12 depicts an isometric view of an embodiment of foldable container 200 that is in an open position. Foldable container 200 is configured to be self-standing in an open position and also be manipulated into collapsed folded position. Foldable container 200 is similar in structure and functionality as foldable container 100, as described herein. However, foldable container 200 includes a hinge portion that enables foldable container 200 to fold into a collapsed position, which will be described in further detail below.

Foldable container 200, in one embodiment, includes a plurality of wall sections to form the foldable walls. For example, a first foldable wall comprises wall sections 210-1 and 210-2, a second foldable wall comprises wall sections 220-1, 220-2 and 220-3, a third foldable wall comprises wall sections 230-1 and 230-2 (also see FIG. 21), and a fourth foldable wall comprises wall sections 240-1, 240-2 and 240-3 (also see FIG. 18).

The combination of the first, second, third and fourth foldable walls (as described above) and bottom portion 250 create an open area within foldable container 200 such that contents (not shown) may be placed within foldable container 200 via opening 260 (or open end).

The wall sections of foldable container 200 are comprised of a material having various properties (e.g., compressive strength, rigidity, flexural strength, modulus of rupture etc.) that enables foldable container 200 to be in a stand-alone open position, as depicted in at least FIG. 12.

Additionally, the material of the wall sections, that form the foldable walls, provides sufficient strength such that contents within the foldable container are less likely to rupture or puncture the container through the bottom portion and/or wall sections as compared to a convention paper bag.

Moreover, the material of the wall sections provides sufficient strength that enables the foldable container to maintain its stand-alone open position with one or more other foldable containers (that include contents) stacked on top of the foldable container.

For example, the wall sections include a substantially rigid material such that the foldable container does not collapse under the weight of an additional foldable container stacked on top of the foldable container similar to the stacked orientation of foldable containers in FIG. 10. The material may slightly flex during the folding to facilitate in collapsing the foldable container.

The material of foldable container can be, but is not limited to, cardboard, corrugated cardboard, etc. It should be appreciated that the material is not required to be single sheet of paper similar to a conventional paper bag. Additionally, the material of the foldable container may be recyclable.

Foldable container 200 includes a plurality of foldable seams to facilitate in folding or collapsing foldable container into a collapsed position, similar to the folding of a conventional paper bag into a collapsed position.

In particular, a plurality of hinge portions form the folding seams of foldable container 200. The hinge portions join the plurality of wall sections with one another.

For example, hinge portion 211 joins wall section 210-1 with wall section 210-2 to form a first foldable wall. Hinge portion 221 joins wall sections 220-1, 220-2 and 220-3 with one another to form a second foldable wall. Hinge portion 231 joins wall sections 230-1 and 230-2 together to form a third foldable wall (see FIG. 21). Hinge portion 241 joins together wall sections 240-1, 240-2 and 240-3 to form a forth foldable wall (see FIG. 18).

Accordingly, the hinge portions form a foldable seam at each joint where each wall sections abuts another. Similarly, the hinge portions form a foldable seam at each joint where bottom portion 250 abuts a corresponding wall section.

The hinge portions comprise a flexible material that enables folding of the foldable container and also joins respective wall sections and bottom portion. The hinge portions, in one embodiment, comprise a different material than the material of the wall sections and/or bottom portion of the foldable container. For example, the hinge portions comprise adhesive tape that has adhesive on at least one side of the tape. It should be appreciated that the hinge portions may be applied to a surface of respective wall sections and/or bottom portion or may be integrated within the edges of the respective wall sections and/or bottom portion.

In various embodiments, foldable container 200 includes handle 270 and handle 272 to facilitate in carrying foldable container. Handles 270 and 272 may be the same material as the foldable walls and/or bottom portion or may be a different material, such as wire.
